My steering is the same as before. The brakes grab right away, it is especially noticable on the highway (I can actually make a direct comparison since my other ti has stock brakes). On the highway at 100+km/h if I apply the brakes the car slows down instantly, while with the stock ones there is a bit of a delay.

The only negative things about 330 brakes is

a) 17" wheels
b) If you are tracking the car you might want to run slightly more agressive pads in the rear to even out the brake distribution.

Also just recently a fellow BMWCC club member test drove my car (the guy is a frequent BMW track school/autocross participant), and his first words when he applied the brakes were: "Holy $hit!!! This car brakes!!!...".

jpropane: it is for my Twin turbo E30, I plan on doing the E36 suspension swap and was wondering if the 330ci brakes were any good or if I should build my own again using C5 corvette discs & the porsche brembo's (I thought this might be a bit OTT).

KIRASIR: Do you get any warping of the rotors when stopping from +100mph, this was my main concern with only 25mm thick rotors.

328x25mm rotors are HUGE! Regular stock 318/325/328 rotors are 286x22mm, and even they don't warp when stopping from 100mph+. There is no way you can warp these rotors on the street. If somehow one warps them on the street then this person shouldn't be driving in the first place. On the track, it's a different story.

Regular 318ti 12mm disks were/are a problem. This is why in 98 all 98+ 318ti were converted to use regular e36 rotors.

So to answer your question: No, not at all on the streets (I haven't been to the track yet).
